These "Superstar" wide 3E kids' shoes were born from children's desire to "run fast." The Power Spring, designed to help them "run fast," assists their running. The weight is approximately 130g per foot in size 17.0cm. 【Power Spring】Moonstar's uniquely developed special rubber is installed in the sole, storing power when stepping on the ground and instantly converting it into propulsion when kicking off. 【Ag+ Antibacterial and Odor-Control】Silver ions inhibit the growth of odor-causing bacteria, providing an antibacterial and odor-control effect. 【Washable Insole】The insole can be removed and washed, keeping it clean at all times. 【Abrasion-Resistant Rubber】The outsole uses rubber that is less prone to wear and tear, providing high durability. These shoes are easy to put on and take off with elastic laces and a band. The grunge-style graphics are a cool and mature point of the Superstar design. We aimed for a product that maintains a sporty feel while making an impact, without being too childish. WIDTH (Foot Circumference): 3E UPPER: Synthetic fiber/Synthetic leather SOLE: EVA/Rubber No box included. Thank you.
